Description
The Juniper JCO400-QDD-ZR-M is a high-performance 400G ZR+ transceiver module designed for long-haul data center interconnects and metro transport applications. Built in the compact QSFP-DD form factor, it supports 400 Gigabit Ethernet over DWDM networks, making it ideal for high-capacity, long-distance optical links. This module operates on coherent DWDM technology and utilizes advanced digital signal processing (DSP) to maintain signal integrity over distances up to 120 km, depending on fiber conditions. Its robust metal housing ensures durability and efficient heat dissipation in demanding network environments.
Equipped with an MPO connector and compliant with OIF 400ZR and OpenZR+ standards, the JCO400-QDD-ZR-M ensures interoperability across multi-vendor platforms. It supports key features like Forward Error Correction (FEC), tunable wavelengths across the C-band, and low power consumption around 20W typical. This unit is hot-swappable, allowing for seamless upgrades and maintenance without service disruption. Ideal for organizations scaling their infrastructure with used or refurbished equipment, it delivers reliable performance and long-term value in high-throughput network deployments.
